  13. Challenges
    • Size Alexa: 8 th most popular site,~ 9% of users, 0.6% pageviews, but how many users/ contributors?
    • Sampling anonymous readers and contributors, non-homogenous community, high turn-over rates
    • Sharing / Open Access (privacy, userid)
  14. Who and Why?
    • Basic demographics
    • 80/20 - 95/5 – 95/95 :-) (Wales vs Swartz)
    • Rise of the Bourgeoisie – Temporal shift of contribution patterns (Kittur et al. 2007)
    • Zealots - Good Samaritans (Anthony et al. 2005)
    • EN: Edits 195M, 4000 editors (non bots) 32.82%
    • Active Wikipedians (5 edt/mth): delta -10% +20%
    • 25% of edits by newbies (less than 1 mth)
  15.  
      • Number of anonymous users
      • Qualitative differences in contributions
      • Survey: More information on types of edits (possible input to modelling contributions)
      • Survey: Motivation for editing
      • Hypothesis: Power-law distribution of total edits, but content production shifts into tail over time, because Samaritans only get involved after sufficient amount of stubs exist
    Who and Why?
  16. Quality
    • Pagerank (Wilkinson)
    • No. of Revisions, Authors, Words ...
    • Peer-review (Nature, Wedemeyer 2008)
    • New concept and understanding of quality
    • Awareness of quality assurance processes
    • Diversity of expertise contributing (Page)
